5 Matching Questions

  1. gene
  2. monosaccharide
  3. alpha helix
  4. dehydration reaction
  5. cellulose
  1. a A chemical reaction in which two molecules covalently bond to each other with the removal of a water molecule
  2. b A discrete unit of hereditary information consisting of a specific nucleotide sequence in DNA (or RNA, in some viruses)
  3. c The simplest carbohydrate, active alone or serving as a monomer for disaccharides and polysaccharides. Also known as simple sugars, the molecular formulas of monosaccharides are generally some multiple of CH20
  4. d A spiral shape constituting one form of the secondary structure of proteins, arising from a specific hydrogen-bonding structure
  5. e A structural polysaccharide of cell walls, consisting of glucose monomers joined by b-1, 4-glycosidic linkages

5 Multiple Choice Questions

  1. A double sugar, consisting of two monosaccharides joined by dehydration synthesis
  2. the level of protein structure referring to the specific sequence of amino acids
  3. the covalent bond between two amino acid units, formed by condensation synthesis
  4. A three-dimensional biological polymer constructed from a set of 20 different monomers called amino acids
  5. A reaction in which two molecules become covalently bonded to each other through the loss of a small molecule, usually water; also called dehydration reaction

5 True/False Questions

  1. hydrolysisA chemical process that lyses, or splits, molecules by the addition of water; an essential process in digestion

          

  2. amino acidAn organic molecule possessing both carboxyl and amino groups. Amino acids serve as the monomers of proteins

          

  3. polysaccharideThe simplest carbohydrate, active alone or serving as a monomer for disaccharides and polysaccharides. Also known as simple sugars, the molecular formulas of monosaccharides are generally some multiple of CH20

          

  4. monomerA long molecule consisting of many similar or identical monomers linked together

          

  5. nucleotideA polymer (polynucleotide) consisting of many nucleotide monomers; serves as a blueprint for proteins and, through the actions of proteins, for all cellular activities. The two types are DNA and RNA
